You may feel dizzy for many different reasons, such as missing meals, drinking alcohol or ear problems.

Don’t worry: While feeling dizzy may worry you, it’s not usually serious and will often get better by itself.

It may not always be easy – or even possible – to find out what exactly makes you feel dizzy.

Action: If you feel dizzy and it doesn’t go away, if you have other symptoms, or if you’re concerned for any other reason, see your doctor to get checked .

What is dizziness?

If you say you feel dizzy, this can mean different things.
For example, you may feel light-headed, faint, giddy, or off-balance.

Fact: Vertigo is a form of dizziness that gives you a feeling of movement, when the world – or you – seem to be spinning or moving around. Ear problems, such as ear infections, can bring on vertigo.

Sensations: You have a strange weakness or numbness in your face, arms or legs, or you find it difficult to walk

Speech: You have problems speaking normally

Symptoms: You have other symptoms that worry you or that you can’t explain

Action: See your doctor if you show any of these warning signs, if your dizziness is severe or if it doesn’t start to improve.

How can I improve my symptoms?

If you feel dizzy, making a few simple changes to your lifestyle can sometimes help to improve your symptoms.
Here are some tips for you to try:
